Performing threat emulation with atomic red team

Skill autohandai/community-skills/performing-threat-emulation-with-atomic-red-team

Executes Atomic Red Team tests for MITRE ATT&CK technique validation using the atomic-operator Python framework. Loads test definitions from YAML atomics, runs attack simulations, and validates detection coverage. Use when testing SIEM detection rules, validating EDR coverage, or conducting purple team exercises.From its SKILL.md

Performing Threat Emulation with Atomic Red Team

Instructions

Use atomic-operator to execute Atomic Red Team tests and validate detection coverage against MITRE ATT&CK techniques.

from atomic_operator import AtomicOperator

operator = AtomicOperator()
# Run a specific technique test
operator.run(
    technique="T1059.001",  # PowerShell execution
    atomics_path="./atomic-red-team/atomics",
)

Key workflow:

  1. Clone the atomic-red-team repository for test definitions
  2. Select ATT&CK techniques matching your detection rules
  3. Execute atomic tests using atomic-operator
  4. Check SIEM/EDR for corresponding alerts
  5. Document detection gaps and update rules

Examples

# Parse atomic test YAML definitions
import yaml
with open("atomics/T1059.001/T1059.001.yaml") as f:
    tests = yaml.safe_load(f)
for test in tests.get("atomic_tests", []):
    print(f"Test: {test['name']}")
    print(f"  Platforms: {test.get('supported_platforms', [])}")
